Transcript

  • 1. MMO REQUIREMENTS • Low latency: We needed to synchronize tens of thousands of clients simultaneously without dropping any data. • Processing:We needed to process hundreds of thousands of threads simultaneously without any error. • Scaling: Ability to scale seamlessly without shutting down the Server,one server per 1000 clients. • Persistance:State of player,game and connection must be maintained at all times. • Redundancy:Redundancy system for the Server and DB structure for world state restoration

  • 5. Advantages FAST! The processor speed stays the same no matter how much load is added onto that particular instance, for eg. Wether its 100 clients or 1000 clients on a particular thread, the cloud will keep processing it at a flat 1.5 Ghz EASY! Amazon offers you a Ubuntu or a Fedora distro which you can upload your code onto and that’s it!Linux is a fantastic open-source platform to deploy any web based app on and theres a wealth of knowledge on the internet to get anybody up and running. REDUNDANCY! We use Amazon’s S3 service to snapshot our server side extensions and Database. In case the server goes down,we can “roll back” to the last known server state. Also helps that there are no bandwidth charges between EC2 and S3 ,making it a fantastic backup option. PLATFORM! Since the whole backend runs off the cloud, we can offer the entire front end and backend as one platform for other customers to build their virtual worlds on and it gives them a seamless and measureable way to scale to their requirements.Software as Service platform, fantastic!
